Product Description
1.Â TheÂ flowÂ pathÂ isÂ simple,Â smallÂ deadÂ zoneÂ andÂ vortexÂ area,Â scouringÂ actionÂ byÂ meansÂ ofÂ theÂ mediaÂ itself,Â whichÂ canÂ effectivelyÂ preventÂ theÂ mediaÂ fromÂ clogging.Â AndÂ hasÂ goodÂ self-cleaningÂ properties.
Â
2.SmallÂ flowÂ resistance,Â flowÂ coefficientÂ smallerÂ thanÂ theÂ singleÂ seatÂ valve,Â equivalentÂ withÂ theÂ flowÂ coefficientÂ ofÂ double-seatÂ valve.
Â
It'sÂ suitableÂ forÂ theÂ caseÂ ofÂ highÂ viscosityÂ fluidÂ containingÂ suspendedÂ particulateÂ matter,orÂ toÂ requestÂ aÂ placeÂ atÂ rightÂ anglesÂ toÂ theÂ pipe.Â ItsÂ flowÂ isÂ generallyÂ bottomÂ intoÂ theÂ side.
